Abstract
ABSTRACT
            Background and Objectives: Citrus fruits and their constituents especially naringin (NR), a natural predominant flavanone, have a wide range of pharmacological activities without toxicity against cancer cells. The aim of this study was to investigate the anticancer effects of orange peel extract (OPE) and naringin (NR) on esophageal squamous cell carcinoma (ESCC) cells.
            Methods: Amount of phenol, flavonoid and antioxidants in OPE was determined using Folin-Ciocalteu procedure, aluminum chloride colorimetric and DPPH assays, respectively. Effects of NR and OPE on viability, wound healing assay and DNA fragmentation using DAPI were investigated. Data were analyzed by ImageJ software and GraphPad Prism 6.0 at significance of 0.05.
            Results: Total amount of phenols, flavonoids and 1,1-diphenyl-2-picrylhydrazyl was 2.83, 2.143 and 60.76 g/100g of OPE. Amount of NR in the dried OPE was estimated to be 5.260 (µg/gr) using high-performance liquid chromatography. Treatment of ESCC cells with OPE or NR decreased viability y of cancer cells in a dose-dependent manner. In addition, both OPE and NR were able to decrease cell migration and increase DNA fragmentation.
            Conclusion: The findings of our study suggest that OPE and NR have anticancer effects on ESCC cells but the anticancer effects of OPE was better than that of NR alone.

Abstract
Background: The incidental discovery of papillary thyroid carcinoma (PTC) in cervical lymph nodes during neck dissection for tongue squamous cell carcinoma (SCC) is an exceedingly rare finding, reported in approximately 0.3 - 1.6% of head and neck squamous cell carcinoma (HNSCC) cases. Differentiating between metastatic PTC and papillary carcinoma arising in aberrant thyroid tissue poses a diagnostic challenge, especially in the absence of a detectable thyroid mass.
Case Presentation: A 35-year-old male presented with a rapidly growing ulcero-proliferative lesion on the lateral border of the tongue for four months. Biopsy revealed moderately differentiated SCC. The patient underwent hemiglossectomy with supraomohyoid neck dissection. Histopathology confirmed SCC with clear margins and no nodal metastasis; however, one cervical lymph node revealed thyroid follicles with cells showing optically clear nuclei. Immunohistochemistry was positive for TTF1 and HBME-1, confirming metastatic PTC. No palpable thyroid nodule was identified, and computed tomography demonstrated only hypodense colloid nodules. Thyroid function tests were normal, and the patient remains disease-free on follow-up without thyroid surgery.
Conclusion: The coexistence of tongue SCC and metastatic PTC in cervical lymph nodes is exceptionally uncommon. The absence of a primary thyroid lesion raises questions regarding the origin - occult metastasis versus transformation in aberrant thyroid tissue. The literature supports conservative management with vigilant follow-up when thyroid imaging shows no evidence of malignancy. Meticulous histopathological examination of neck dissection specimens in HNSCC is vital. Management should be individualized, balancing surgical intervention and surveillance based on clinic radiologic findings.

Abstract
Background: Basal cell carcinoma is the most common skin cancer. It accounts for 80% of all non-melanoma skin cancers. It most commonly occurs in sun-exposed areas. 0.094% of the cases occur in the inguinal region.
Case presentation: A 70-year-old male presented with swelling in the left inguinal region for 6 months, diagnosed as malignant melanoma based on clinical and cytological features and finally as pigmented basal cell carcinoma by histopathology and immunohistochemistry.
Conclusion: All pigmented lesions are not melanoma. Pigmented basal cell carcinoma is an important differential diagnosis for malignant melanoma irrespective of the site, size, and clinical picture. We take this opportunity to reiterate the chances and reasons for the misdiagnosis of basal cell carcinoma in cytology smears.

Abstract
Background: Gastric cancer (GC), particularly adenocarcinoma, remains a major global health burden with high mortality, largely because of late-stage diagnosis and the limited availability of reliable biomarkers for disease monitoring. Lipid metabolism plays a crucial role in tumor biology, and serum lipid-related markers, including apolipoproteins, have been proposed as potential non-invasive indicators of tumor progression. This study aimed to evaluate the association between serum lipid profiles and tumor stage and histological grade in patients with gastric adenocarcinoma.
Methods: Fifty patients diagnosed with gastric adenocarcinoma were enrolled. Serum levels of total cholesterol, triglycerides, HDL-C, LDL-C, ApoA1, and ApoB were measured. Patients were categorized into early (Stages I-II) and advanced (Stages III-IV) tumor stages, as well as into moderately differentiated versus poorly differentiated grades. The Shapiro-Wilk test was used to assess data normality. Parametric and non-parametric tests were applied accordingly. A p-value < 0.05 was considered statistically significant.
Results: ApoB was the only parameter showing a significant association with tumor stage. Patients with advanced-stage GC had significantly lower mean ApoB levels than those in early stages (52.4 ± 2.6 vs. 63.4 ± 5.2 mg/dL, p = 0.042). No statistically significant differences were observed in ApoA1, HDL-C, total cholesterol, triglycerides, LDL-C, or VLDL with respect to either tumor stage or histological grade.
Conclusion: ApoB levels appear to decline with advancing tumor stage in gastric adenocarcinoma, suggesting a potential role as a marker for evaluating disease burden. Although no association was found with tumor grade, further validation in larger prospective studies incorporating metabolic and inflammatory covariates is warranted.
